The LHCb collaboration has reported an intriguing new result in its quest to test a key principle of the Standard Model called lepton universality. Although not statistically significant, the finding—a possible difference in the behavior of different types of lepton particles—chimes with other previous results. If confirmed, as more data are collected and analyzed, the results would signal a crack in the Standard Model.
